Question

1. wind can cause erosion that changes the surface of the earth. wind erosion can have negative effects on the environment by removing soil and polluting the air during dust storms. which of the following landforms are created by wind erosion? sand dunes and arches arches and faults deltas and sand dunes meanders and deltas 9. which best describes a landslide? erosion caused by ice erosion caused by wind erosion caused by a river erosion caused by gravity 3. the freezing and thawing action of water affects a rock by gradually breaking down the rock into smaller pieces. chemically changing the rock leaving behind sedimentary particles from evaporated solutions. transforming the rock into igneous rock

Explanation:

1. Sand dunes are formed as wind - blown sand accumulates. Arches can be formed by wind erosion as well as other processes like water erosion. Deltas are formed by river deposition, meanders are river - related landforms, arches and faults are related to tectonic and other geological processes not mainly wind erosion.
2. A landslide is the movement of rock, debris, or earth down a slope under the influence of gravity. It is erosion caused by gravity.
3. The freezing and thawing action of water is a form of mechanical weathering. When water freezes in the cracks of a rock, it expands, and when it thaws, it contracts. This repeated action gradually breaks the rock into smaller pieces.

Answer:

1. Sand dunes and arches
2. Erosion caused by gravity
3. Gradually breaking down the rock into smaller pieces
